Working Principle

The Kaishan M30C DTH hammer operates on the principle of down-the-hole drilling, where the hammer is positioned directly behind the drill bit at the bottom of the hole. Compressed air is supplied through the drill string to the hammer, driving a piston that strikes the bit with high impact energy. The piston reciprocates rapidly, delivering thousands of blows per minute to the bit, which crushes the rock. Simultaneously, the exhaust air from the hammer flushes the cuttings out of the hole through the annular space between the drill pipe and the hole wall. This continuous process allows for efficient drilling in hard rock formations. The M30C's valving system controls the air flow to ensure optimal impact energy and air consumption. The hammer's simple design and robust construction enable reliable operation even in the most demanding conditions. The use of high-quality materials and precision machining ensures that the piston and cylinder maintain tight tolerances, maximizing energy transfer and minimizing wear. This results in faster penetration rates and longer service life, making the M30C a cost-effective solution for a wide range of drilling applications.
